From a builders standpoint, now is an excellent time to build! The interest rates are at historic lows and you can even lock in rates on construction loans long term before you break ground. Prices are fantastic and you can get the best crews and more service from your builder right now. There is nothing like a new home and getting to make it "your own". If built in the right area a new home will appreciate much faster in value than an existing home.
However, only owning the home 6 months and then adding $10,000 in improvements it is not likely that you will be able to sell it and break even after paying a list/sell commission, transfer fees, moving, and everything else. If you are okay with that scenario, go ahead and at least take a look. It doesn't cost anything to get a market analysis from a Realtor, or to sit down with a builder and discuss plans and pricing.
